Tangential but hilarious: back in the day, the British were buying fragments of dinosaur fossils from China. Unfortunately, they paid per fragment, so it was much more profitable to break the specimens into bits before sending them.
There's also the case of a dolphin that was trained to collect plastic trash (they paid it in fish). The dolphin realized that it could get more fish by tearing the plastic into shreds.
